Because some versions of Qt require a non-const QRegExp, we copy _embedInfos to

a non-const variable:

EmbedInHtml embedInfos(_embedInfos) ;

However, since EmbedInHtml is the base class we lose any information added in
the derived class, which causes a problem with EmbedInHtmlImg when we do a
static_cast to what should have been the proper type here:

const EmbedInHtmlImg& embedImg = static_cast<const EmbedInHtmlImg&>(embedInfos);

embedInfos is not an EmbedInHtmlImg any more, just a mere EmbedInHtml.

We could const_cast the QRegExp object instead but let's keep it simple and
remove the embedInfos constness from the method's signature.
